# Find Boost's libs (currently date_time) and makes sure boost includes are available.
#
# We use a custom cmake module instead of cmake's FindBoost as otherwise we'd have to:
# - Run cmake's FindBoost twice to make sure it picks up the shared and static version of the lib.
# - Have a check to make sure we're not picking up the system's boost.
#
# Less (and simpler) cmake lines are required than if we were to work around cmake's FindBoost
# behavior.
#
# This module defines
#  BOOST_DATE_TIME_SHARED_LIB, path to boost's date_time shared library
#  BOOST_DATE_TIME_STATIC_LIB, path to boost's date_time static library
#  BOOST_INCLUDE_DIR, patch to boost's headers
#  BOOST_DATE_TIME_FOUND, whether boost has been found
